The Chemistry Pilot :where
NORTH SEA
BLACK SEA
MEDITERRANEAN SEA
Regional Leaders:North Sea – NERIBlack Sea– MHIMed Sea – HCMR
The Chemistry Pilot : what
-parameters choice based on MSFD requirements, from 8 groups of compounds, in 3 matrices( water, biota, sediment),
17 selected parameters for product generation.
The Chemistry Pilot : How
Based on SeaDataNet :
• An efficient distributed Marine Data Management Infrastructure for large and diverse sets of data deriving from in situ and remote observation of the seas and oceans.
• Actively involved in standards implementation following INSPIRE;
• An european de-facto standard with: 44 partners and 14 subcontractors from 35 countries european and not.
The Chemistry Pilot : How
Principle of “ADOPTED AND ADAPTED”
SDN Standards for metadata ,data and products :
• for metadata (xml ISO 19115 ISO 19139) CDI;
• for common terms Standard Vocabs (P021,P011,P061...);
• for background data exchange ASCII format ODV,
SDN Infrastructure:
• Service to access data with data policy management CDI mechanism,
• Service for users registrations SDN Security Services,
• Service for discovery, visualization and downloading of products SDN Products viewing services
SDN Softwares:
• MIKADO → metadata mapping and xml generator
• NEMO → data formatting tool
• DIVA software → gridded data products and error maps as NetCDF files,
• ODV software → for “time series” products generation and QC
The Pilot Project
Work Packages: • WP1 - Project Coordination
• WP2 – Data collection and metadata compilation
• WP3 – QC/QA and data products
• WP4 – Technical development and operation
• WP5 – Analysis and Evaluation
• Partners: 25 partners;
• OGS coordination;
• Contract had a duration of 3 years from June 2009 to June 2012;
The Pilot ProjectWP2 Data collection and
metadata compilation :
All partners collected and updated : Data → ODV file → managed by Reg. Leaders at level of the 3
Regional data pools → (de-centralized) Metadata → CDI entries → Maris (centralized)
All partners gave access to:
• metadata (unrestricted);
• and data according to the data policy as agreed with the data ORIGINATOR.

The Pilot Project:challenge to face along the path from DATA to
PRODUCTS Data complexity: • from 8 groups of compounds;• 3 matrices (sediment, water column and biota);• 17 selected parameters for products generation;
Heterogeneity:• Of the sampling/data distribution (coastal points time
series Vs homogenous sampling at basins level);• Of measurement methods (instrument, method, target
species, target basis, grain sizes).
The Pilot ProjectWP3 QC/QA and data products:
• The analysis of available data;
• The Expert workshop with contribution of the Marine Conventions;
• Highlighted 2 main substets from the available data :
Expert workshop, summary of decisions to highlight data features with Products generation:
-Standard Diva Interpolated maps produced for parameters with homogeneous and suitable data coverage, measured on basin scale;
-“Time series plots”. Showing station maps linked to plots of measured time series. This for not homogeneous data as:
•coastal points repeated in time,•datasets with fragmented coverage.
Not homogeneous ditributionIn time and space (basins)
Homogeneous ditributionIn time and space (basins)
Data products
DIVA interpolated maps:
– Focus on nutrients in the water column based on data availability;
– Focus on annual and seasonal scale based on data availability;
– Interpolated maps generated by Diva software;
– Metadata file generated by DivadoXML script;

Data productsTime Series plots:
-Focus on the parameters with fragmented coverage (spatial/temporal);
-suggested use of ODV software for plots generation;
-ratio of 1plot:1station:1parameter:1depth;
-metadata collected in a INDEX file (http://www.data-assimilation.net/mediawiki/index.php/OceanBrowser#Observation_index_files )
Recommendations:
-to avoid plots for stations with less than 3 points;
-to avoid linkage lines between single points;
-to provide TS plots in vector format (as SVG);

The Pilot Project
WP5 Analysis and Evaluation: 2 online questionnaire
Lessons Learned/Open issues from Pilot
• QC for «exotic parameters» (eg:contaminants...) no spikes are detect for them, they are events. At the moment not enough data to calculate regional ranges.
• Lack of «Under detection limit» information;
• Technical development/usersfriendliness: Finalization of products metadata catalogue to load and
search Maps metadata /Time series plots metadata;
• Improvements of web interfaces search criteria as highlighted by SDN2 userpanel and Chemistry Lot users;
• Improvement of handling of Chemical Parameters metadata with Common Vocabs (transparency/flexibility);
• Need of group of experts for the data-products periodic validation for each regions + workshop.
The New Phase (MARE/2012/10)
Enlarged partnership: 32 partners + 14 sub-contractors = total of 46 participants (about twice!) coordinated by OGS;
Official starting? Kick-off meeting: Trieste, 3rd -5th June 2013; New parameters: chlorophyll, silicates, partial pressure of
dissolved gasses, plastics, acidity; 3 matrices: water column, biota, sediment; The portal should cover all European waters; New products: coastal visualization + a proposal for
assessment tool; Specific focus on Coastal Data.
The New PhaseThe portal should cover all European waters
Note: This map is derived from the EU Tender document but lacks the Norwegian sea
The parameters:
The New Phase:WPs• WP0- Project Management • WP1- Data collection and metadata compilation in sea regions• WP2- Data Products generation in sea regions• WP3 - QA/QC - Validation - MSFD interaction• WP4- Portal development and operation • WP5 - Analyses and Recommendations
Collaboration with other projects/activities:• SDN since the pilot phase;• Emodnet Lots ongoing;• ODIP for this second phase;• ...and open dialogue with Marine Conventions.
Regional level:
Data harvesting (WP1) and products generation (WP2) will be always organized at Regional level. This time 5 sea regions have been defined as:
• Greater North Sea (including Norwegian Sea and Celtic Sea);
• Atlantic Sea (including Atlantic Coast and Macaronesia);
• Baltic Sea;
• Black Sea;
• Mediterranean Sea.
Ongoing activity to face the Pilot open issues:
• QC for exotic parameters:
• Open dialogue with MSFD requirements/guidelines;
• Data harvesting will provide new data for regional ranges;
• Open dialogue with Marine Conventions experts;
• Efforts to collect «detection limits» for an inventory in the different areas;
A technical meeting under definition ( September?) for: Finalization of products metadata catalogue;
• Improvement of web interfaces search criteria ;
• Improvement of handling of Chemical Parameters ;
• the data-products periodic validation:
• Regional experts group already searching for candidates;
• QC workshop to be organized at month 12.
What is expected from the activity within 2014
• Sea Regions definition (November 2013?);
• Updated datasets for the 5 Regions;
• First release of updated classic products (interpolated maps ans TS);
• A test case for an assessment tool;
• At M12 first validation workshop with experts from: Marine Conventions, MSFD and WG-DIKE.
